Dannii Minogue: I haven't read about myself in Simon Cowell's 'smug' biography but I wish him the best
Simon, 52, told the book's author Tom Bower that it was Dannii's 'sexy clothes and tits' which attracted him to her.
'I haven't read the book but I've been told about the excerpts that relate to me and the speculation about my private life,' says Dannii, 40.
'From what's been reported they put hundreds of hours into making this book and Tom is a respected journalist. They looked very pleased with it all at their launch.
'I'm sure it makes for a great read and I wish them all the best.'
Tom describes in In Sweet Revenge: The Intimate Life Of Simon Cowell how Simon and Dannii's fling kicked off when Dannii joined The X Factor judging panel in 2007 but it 'petered out' while the mogul was in America.
Dannii - who'd been tipped to replace Kelly Rowland on this year's series of the talent show - insists she didn't turn the invitation down because of the book's allegations.
'I was offered the chance to return but I decided it wasn't the right thing for me, as yet again it didn't fit in with the commitments I'd already made to Australia's Got Talent,' Dannii tells Glamour.
'I had four incredible years on The X Factor but the show has moved on, and so have I.'
